TRAINING SEQUENCE DETERMINING METHOD AND RELATED DEVICE |
(57) This application provides a training sequence determining method and a related device.
The method in embodiments of this application includes: An ONU receives a first message
sent by an OLT. Then, the ONU determines a target training sequence based on the first
message, where the target training sequence is used to determine a working parameter
of an equalizer in the OLT. Further, the ONU generates a first data frame including
the target training sequence. In this application, the OLT may perform training based
on the received target training sequence to determine the working parameter of the
equalizer in the OLT, so that the equalizer compensates for channel impairment and
effectively eliminates ISI, thereby improving performance of the OLT.
